IMPROVEMENT IN PARLO R-STOVES.

Spccilication forming part of Letters Patent No. 35,506, dated June l0, 1962.

To all whom it may concern,.-`

Be it known that I, GARDNER CHILsoN, a citizen of the United States of America, and a resident of Boston, inthe county of Suffolk and State of Massachusetts, have invented an Improved Parlor-Stove, which l do hereby declare to be fully described in the following specication, and illustrated by the `accom panying drawings, of which- Figure 1 is a front view, Fig. 2 a side elevation, and Figs. 3 and 4 vertical sections, of it. Fig. 5 is a horizontal section of it, the plane of section being through the oven.

My stove is notA only for heating an apartment, but particularly for warming that part of the same which is near the door-ea matter in which many stoves fail. Furthermore, my stove is constructed so as to afford a properventilationof the room without abstracting from it the great body of air which is close to the floor. i With my ystove baking,y

boiling, or various other culinary operations can be carried on at the same time. The stove is employed for the purpose of heating an apartment.

In the drawings, A exhibits a'close hollow box or base, on which the body or outer cylincal case, B, and the inner or hre-chamber case, C, of the `stove are supported, one of these cases being arranged Within the other, and so as to have a fluespace between them. In the lower part of the inner case there is an ashchamber, E, for the reception of an ash box or drawer, F, such chamber being made to open through the front of the case and to have its yash-drawer furnished with an induction airvalve register, H.

VThe re-place may have a soapstone or firebrick lining, a, and should be furnished with a grate, I, having two journals, b o, to rest and revolve in Suitable bearings, d e. These bearings should be so constructed as not only to allow the grate to be moved out of them, but to have the end of its front bearing inserted in a revolublc grate-rotator, G, which is entirely,

1separate fromthe grate and rests in a bearing or round socket, f, made within a frame, g, ar,` ranged with respect to the mouth of the ashchamber, as shown in the drawings. The ro tator G projects through and out of its socket and has the part h, so projecting, made starshaped or prismatic, in order that a key or 1ei ver maybe applied to it for the purpose of uputting the rotator G in revolution in such manner as to produce the motions of the grate, such as at any time may be desirable, whether for discharging either fuel or ashes therefrom.

The advantage of the graterotator made and applied in a socket, as described, is that while it will admit of removal of the grate either for renewal or repairs it will produce with its socket a tight joint, through which ashes can not escape while the grate may be in the act of being rotated.

The inner cylinder, C, is not so high as the surrounding case B, which is surmounted by a conical enlargement-ring, K, on which auother cylindrical case, L, is placed, the lat ter case being largerin diameter than the case B. An oven, M, consisting of a cubical or square chamber or box with an open end, is placed Within the case L and opens through it, the oven being surrounded on its three ver-- tical sides bythe case L, and so as that the latter may be in contact, or nearly so, with the juncture of each turn of the sides In this way there will be a flue-space against each of the two sides and the rear end of the oven, these dues being marked N 0"' N. These iiuespaces all lead outof the fire-chamber and open into another or domed chamber, P, arranged over the oven and provided with a boiler-hole, s, and cover t, as shown in the drawings.

A short pipe, R, provided with a damper, S, leads horizontally out of the flue-space between the cases B and C and opens into a vertical pipe, T, which rises from the base Aand leads out of the hollow part or chamber thereof.. A short pipe, Il, extends laterally out of the pipe T and on a level with the pipe R. The said pipe U has at its outer end an airregister,V, bywhich air may be admitted into the pipe T, and the amount of such airbe in4` creased or diminished, as circumstances may require, whetherfor Ventilation of the apartment in which the stove may be situated or for affecting the draft of the stove.

The lower plate, '1, of the oven is made dishing or concavo-convex around a circular opening, m, made through it, the convexity of the said plate being toward the fire-place. The object of this is threefold. It facilitates thev application of a cover, n, to such opening; it strengthens the said oven-plate y and prevents it from being warped and broken by the heat of the fire, and, finally, it operates to deflect the heat and smoke toward the sides of the stove and into the lateral vertical fiue of the oven.

That part of the top of the base which is within the ash-chamber is furnished with an opening, o, and a cover, p, therefor. This hole is for the purpose of enabling a shovel or other proper implement to be introduced at any time into the base, in order to clear it of any ashes or deposits which may have formed or been collected therein.

By removing from either of the holes m s its cover a kettle or boiler may be introduced into such hole.

In order to have sufeientlylarge fine-spaces against the two sides and rear end of the oven, and to properly direct the heat of such fines, I employ the enlargement-ring, as above described. The natural tendency of the heat is to rush upward through all the three fines. Thistakes place when the fuel is first set on fire; but soon afterward the draft will be up the side fines and into the domed chamber above them, and from thence down the tlue'at the rear of the oven, and thence into the Huespace between the two cases B and C. From thence the smoke and heat will escape th rough `the direct-draft pipe R, provided its damper be open; otherwise they will descend into the base of the stove and pass out of the same, and'finally make their exit by the upright pipe T. By arranging the Ventilating-register close vto thejuncture of the two exit-pipes I have found that there will be no such back currents or reacting draft tending to force the smoke and volatile gases out of the joints of the stove as result when the register is located in or close to the base of the stove, where there is always r the weakest draft. With my arrangement of the register the descending draft, or that through the base, will be favored or facilitated in passing into the vertical exit-pipe, the action of the pipe and register with respect to the base being analogous to that of a watersiphon. Besides, the said arrangement of the air-register is more advantageous with reference to its action on the direct-draft pipe than would be the case were the register placed below it and close to the base.

The base of my stove contains a chamber extending entirely underneath the ash-chamber, and therefore it will hold a large amount of smoke and heated volatile products, which being thus kept in the vicinity of the door will cause the base to radiate heat to great advantage into the lowest portion of the apartment in which the stove may be. The ashes in the ash-box, covering the entire bottom of the ash-chamber, will, as a non-conductor of heat, operate to prevent the abstraction of the heat by the bottom of the ash-chamber, and as a consequence such heat will be diffused against and into the edges and bottom of the base.

I claim-` l. The separate grate-rotator as made not only with a grate attachment or device for connecting the grate with it, but with a head or its equivalent for receiving a key or lever.

2. The construction of the ash-pit mouthframe with a socket for the reception of the said grate rotator made separate from the grate, and also in manner and so as to operate the grate, as specified.

3. rlhe arrangement of the conical enlargementring, the fire-chamber, the oven, and the flue-spaces about the sides and top of the oven.
